FSA's OS-99 CSI Road Stem achieves a lot for its svelte stature. Made with a skeleton of CNC'd aluminum and wrapped with 3K carbon, the CSI is super stiff, which tightens up your steering and handling. It's super light, too, helped by the carbon wrap, the sculpted 4-bolt faceplate and titanium hardware.
